Right now the attitude of the team is that we're just trying to make a great game that people will enjoy. Charging for it would mean less people enjoy it. If it becomes super popular at some point we may do microtransactions, selling cosmetics or something.

I never realised that 'free' was such a selling point for a mod. I mean, it's a mod. Of course it's free. We can't sell it because we haven't licensed the engine, we've used valves work (code and art) - there's a whole bunch of stuff that is straight up not ours in DA and we therefore can't sell it.

Q. Can I sell my Source Engine game on Steam?A. Yes, but there are a few requirements:

You will need to complete an additional agreement for distributing a paid Source Engine product on Steam.If you are using the RAD tools included with the Source SDK, you will need to contact RAD for information and cost associated with licensing MILES and/or BINK.For any Source Engine game that charges money, Havok needs to be paid a licensing fee of $25,000 for the physics engine. You will need to pay this fee up front before making your game available for sale on Steam.You can only sell your Source Engine game via Steam unless you get a full Source Engine license.
